挖掘机冷车热车憋车故障需要注意什么?

日期:2023-04-19   来源:http://www.dybocheng.com
简单来说,挖掘机憋车就是发动机的转速急剧下降,造成发动机冒烟甚是熄火。
Simply put, holding the excavator is a sharp decrease in engine speed, causing the engine to smoke or even stall.
挖掘机憋车故障有三种表现形式分别是:热车憋车冷车憋车冷车热车都憋车,下面分别说下每种情况的原因。
There are three types of manifestations of excavator car holding failure: hot car holding car, cold car holding car, cold car holding car, and hot car holding car. Below are the reasons for each situation.
一挖掘机热车憋车
A hot excavator holding the car
当发现挖掘机热车憋车故障的时候,需要及时进行维修,造成该故障的常见原因有以下五点:
When a hot excavator is found to have a stuck car malfunction, timely maintenance is required. The common causes of this malfunction are as follows:
有黑烟可能是挖掘机油路输油泵发动机进气发动机三滤等有故障。
The presence of black smoke may be due to a malfunction in the excavator's oil circuit, fuel pump, engine intake, engine triple filter, etc.
液压泵或者分配阀泄露,造成泵功率大于发动机功率。
The hydraulic pump or distribution valve leaks, causing the pump power to exceed the engine power.

因油路问题造成的热车憋车,应及时检查油路,有可能是油变质或太脏。
If a hot car is stuck due to oil circuit problems, the oil circuit should be checked in a timely manner, as it may be due to oil deterioration or too dirty.
热车是高压油泵内泄增大造成的憋车,需要校油泵。
A hot car is caused by increased internal leakage of the high-pressure oil pump, and the oil pump needs to be calibrated.
泵调节器磨损泵阀组压力流量过大泵内部组件磨损等等原因。
The pump regulator is worn, and the pressure and flow rate of the pump valve group are too high. The internal components of the pump are worn, and so on.

二挖掘机冷车憋车
Two excavators are cold and suffocating
造成挖掘机冷车憋车原因可能是以下几点:
The reasons for the excavator to freeze during cold driving may be the following:
发动机转速或者负载功率不足。
Insufficient engine speed or load power.
挖掘机的泵压力不正确。
The pump pressure of the excavator is incorrect.
发动机气门间隙过大或过小。
The engine valve clearance is too large or too small.
电磁阀电压值不足。
The voltage value of the solenoid valve is insufficient.
柴油标号错误,天冷柴油粘度大,供油不足。
Incorrect diesel label, high viscosity of cold diesel, insufficient fuel supply.
三挖掘机冷车热车都憋车
Three excavators, cold cars, hot cars, all suffocating
如果要是挖掘机冷车热车两种情况都憋车呢?这种故障一般在二手机这些使用年限较长的挖机上出现。发生该故障的原因有:
What if the excavator is cold and the car is hot, and both situations hold the car? This type of malfunction usually occurs on excavators with longer service life such as second mobile phones. The reasons for this fault are:
柴油泵(高压油泵)油嘴工作不良。
The nozzle of the diesel pump (high-pressure oil pump) is not working properly.
发动机功率过大。
Excessive engine power.
泵阀组压力流量过大。
The pressure and flow rate of the pump valve group are too high.
因为较长时间不换油造成的等等。
It is caused by not changing the oil for a long time, and so on.
